 Breeding Program

HZPC Americas Corporation's success is based in part on the skill of our potato breeders and the strength of the potato varieties they have developed. The varieties reflect our policy of matching products to customers. HZPC varieties have been developed for tolerance to extreme ranges of climate, for both intensive and marginal production environments and for regions having extremes of disease pressure. 

Consumer expectations for color, texture, taste and shape have been maintained along with enhanced performance. Excellent varieties have also been developed for the potato processing industries where suitable varieties for french-fries, potato chips, snacks, salads and industrial starches are required. 

Variety development is a time consuming process, from the initial pollination of potato flowers to the eventual selection of a truly better variety, more than ten years of evaluation and testing takes place.

HZPC - Variety development

In fact the HZPC screening process, carried out on a global basis, now identifies only one better variety from an initial population of more than four hundred thousand seeds. Only the best become fully-fledged HZPC varieties.

 Production

Each HZPC variety is derived from classical plant breeding processes. Along with this traditional method, modern seed potato production techniques are carefully employed to increase the volume of seed potatoes to meet growing demands for HZPC seed potatoes.

HZPC varieties have the genetic potential to perform in their designated production areas. However, quality of the seed potatoes must also be high so producers can realize the full potential of a variety. A successful crop depends on high quality seed.

HZPC - Seed Production

HZPC varieties are grown by the best American and Canadian seed potato producers. The potatoes are grown on their own account and the crop is sold by HZPC or by affiliate marketing agents. HZPC seed potato producers have excellent reputations and grow seed potatoes in select isolated areas in soils ideal for healthy potato production.

HZPC - Production

Official crop inspections, post harvest tuber inspections, diagnostic tuber health assessments and certification agencies of State and Federal status serve to validate the reputations maintained by our producers.
